[CentOS] Iptables not save rules

Hello,

I have been using ipset to blacklist badbots. Works like a champ!

The only problem is if I do a  system reboot, I lose the ipset and the rule.

I changed /etc/sysconfig/iptables.conf to:

IPTABLES_SAVE_ON_RESTART="yes"
IPTABLES_SAVE_ON_STOP="yes"

And followed the instructions in:

https://www.centos.org/forums/viewtopic.php?t=3853 

The changes are still not saved.

The rules show up in the running /etc/syscong/iptables but are lost on a
reboot.

Also, firewalld is not installed. This is a CentOS 6.8 system.

One question, do I need to stop iptables before I add the rules? I have seen
examples where sometimes they do and sometimes they don't.

TIA
